Realizing digital signal demodulation on
the general computer is an important research direction in the field of signal
processing in recent years. In this paper, the algorithm of BPSK signal demodulation
which has high real-time requirements is researched on the general computer.
According to the characteristics of “CPU + GPU” heterogeneous computing, the
parallel computation model of digital communication is put forward, and BPSK
signal demodulation is realized on CUDA platform. Test results show that the
computing time ratio of 1:1.7, when
？the bit error rate can
be achieved 10?5.
